This paper presents a heuristic to solve the Multidimensional Multiple-choice Knapsack Problem (MMKP), a variant of the classical 0–1 Knapsack Problem. We apply a transformation technique to map the multidimensional resource consumption to single dimension. Convex hulls are constructed to reduce the search space to find the near-optimal solution of the(More)
Efficient routing in mobile opportunistic networks and Delay Tolerant Networks (DTNs) in particular, is a challenging task because human mobility patterns are hard to predict. Several recent work have shown the importance of communities in efficient routing of messages in DTNs. However, real time community detection in DTNs is a complex and time consuming(More)
